Intertechnik HQ58/4.7/140 | 4,7 mH | 0,19 Ω | 5% | 15 AWG

The Intertechnik HQ58/4.7/140 is a premium roller core coil engineered for audiophile-grade loudspeaker crossover networks. This 4.7 mH iron core inductor delivers exceptional stability and low distortion, making it an ideal choice for high-fidelity audio systems where precise frequency filtering is paramount. Whether you are building custom speakers, upgrading existing designs, or restoring vintage audio equipment, this coil ensures accurate signal separation and consistent performance across demanding listening environments.

Constructed with a 15 AWG wire diameter of 1.4 mm, the coil achieves a remarkably low DC resistance of just 0.19 Ω, minimising power loss and maintaining signal integrity even under high current loads. The generous 58 mm outer diameter and 28.8 mm core diameter provide ample winding space, while the 4.8 mm centre hole facilitates secure mounting. With a tolerance of ±5%, this component guarantees reliable and repeatable results in your crossover circuits. The robust iron core design further reduces magnetic saturation, preserving audio clarity at higher volumes.

Ideal for both DIY enthusiasts and professional audio engineers, this Intertechnik coil combines meticulous craftsmanship with technical precision. Its durable construction and carefully specified parameters make it a trusted choice for achieving transparent, natural sound reproduction in any speaker project.
